Ch 14 # 18c In 1986, a gargantuan iceberg broke away from the Ross Ice Shelf in Antarctica. It was approximately a rectangle
160km
long,
40.0km
wide, and
250m
thick. (c) How many years would it take sunlight alone to melt ice this thick, if the ice absorbs an average of
100(W)/(m^(2)),12.00
h
per day? (Hint: density of ice is
917k(g)/(m^(3))
, the latent heat of ice is
3.34\times 10^(5)(J)/(k)g
, the area of the iceberg is given by the width and length of the iceberg, and
P=(W)/(t)
. What is doing the work to melt the iceberg?)
